Mechanical parts in the use of products is very important, is an indispensable part of mechanical equipment, as the transmission parts of mechanical equipment, the use of slewing drive also plays a very important role. As a mechanical transmission part, the rotary driving force needs to support the whole mechanical equipment to carry on the operation, so the use of slewing drive brings great help to the work. However, when it comes to slewing drive, there are a lot of errors to avoid in the process of its use, so the following for you to popularize this content.
Selection of mounting support for slewing drive
Matters to be noted in the process
About nuts and bolts
The mounting support of slewing drive must be rigid enough and the mounting surface should be flat. Before assembling the slewing drive, the support should be de-stress treated to reduce the deformation of the slewing drive support. The contact surface of the support and the slewing support must be cleaned during assembly.
1、In the process of use, attention should be paid to the change of noise and the change of rotation resistance torque, such as abnormal phenomenon should be cleared immediately.
2、Slewing drives must be lifted or stored horizontally, please do not lift or store vertically to avoid deformation or drop damage.
3、the slewing drive shall carry out the meshing inspection of the gear before the bolt is fully tightened, and its meshing condition shall meet the requirements of gear accuracy: that is, the contact spots distributed on the tooth surface after the gear pair is operated under slight braking shall not be less than 25% in the direction of gear tooth height and not less than 30% in the direction of gear tooth length.
1、In order to ensure the reliability of bolt work and avoid the shortage of bolt pre-tightening force, the pre-tightening torque of bolt should be checked separately after the first 100 hours and 500 hours of slewing drive work.
2、When tightening the nut, lubricating oil should be applied to the thread of the bolt and the end face of the nut, and it should be tightened evenly and evenly in the circumferential direction with a torque wrench. The pretightening torque on each bolt should be approximately uniform during the last tightening.
Slewing drive as a mechanical parts products play a very important role in our life, we should understand the use of slewing drive need to pay attention to the content. In addition, as mechanical products, we usually use when also pay attention to maintenance, in order to avoid the use of slewing drive process errors, we had better do a good job in advance inspection.
